      <h4><a class="xref" href="CADability.Attribute.Filter.html">Filter</a></h4>
      <section><p>This class filters <a class="xref" href="CADability.GeoObject.IGeoObject.html">IGeoObject</a>s according to their attributes or other properties.
A <a class="xref" href="CADability.Project.html">Project</a> contains a <a class="xref" href="CADability.Attribute.FilterList.html">FilterList</a> which contains Filters. The task of a filter
is to decide, whether a IGeoObject is accepted by this filter or not. The <a class="xref" href="CADability.Attribute.FilterList.html">FilterList</a> is
used by the <see cref="!:SelectObjectsAction"></see> to decide, whether an object may be selected or not.
Filters may also be used for other purposes. In this standard implementation the attributes of a IGeoObject
and the type of the object are used to accept or reject an object.
You may derive a class from this Filter class and handle the static <a class="xref" href="CADability.Attribute.Filter.html#CADability_Attribute_Filter_Constructor">Constructor</a> delegate
by constructing your own filter. In your derived class you can use any criteria of a IGeoObject
for filtering, e.g. the contents of <a class="xref" href="CADability.GeoObject.IGeoObject.html#CADability_GeoObject_IGeoObject_UserData">UserData</a>.</p>
</section>
      <h4><a class="xref" href="CADability.Attribute.FilterList.html">FilterList</a></h4>
      <section><p>A FilterList is a list of <a class="xref" href="CADability.Attribute.Filter.html">Filter</a>s. The <a class="xref" href="CADability.Project.html">Project</a> owns a FilterList which is used
by the <see cref="!:CADAbility.Actions.SelectObjectsAction"></see> to decide which <a class="xref" href="CADability.GeoObject.IGeoObject.html">IGeoObject</a>s may be selected or must be rejected.
You may add a handler to the <a class="xref" href="CADability.Attribute.FilterList.html#CADability_Attribute_FilterList_PreFilterEvent">PreFilterEvent</a> event to do your own filtering or use the
default filtering machanism (or both). The FilterList of the project is displayed in the ControlCenter
and may be interactively manipulated.</p>
